OKI testina LED (4W/4W+/6e/w/8wL/10e/OF)

Faded prints, streaks, or a completely blank page often point to a failing LED print head. This OKI LED head restores sharp, consistent output by generating the precise electrostatic image on the drum. It is the exact component responsible for exposing each dot of toner, so a worn or damaged head directly degrades print quality. Replacing it brings back the crisp text and vivid graphics your OKI printer delivered when new.

It suits environments where print quality is critical—offices, print shops, and graphic departments—and where downtime must be minimized. If you are comfortable opening the printer and following service procedures, this part is a cost-effective alternative to a full service call.

Tips

Before replacing the LED head, clean the printer interior and check the drum unit for damage. Handle the LED head by its edges and avoid touching the LED array—oils from skin can affect light output. After installation, run a calibration or alignment page from the printer menu to ensure optimal color registration. Keep the old head as a spare for troubleshooting if the issue persists.
